Packaging for bulky articles with false side gusset

ABSTRACT

A new package for storing bulky goods is disclosed. The package is formed from a bag having a width and depth at its base portion and meeting at a top edge, the top edge having no depth. Due to the top edge having no depth, the width of the material on the top portion of the package extends out further than the width of the material on the base portion. To create a package having streamlined aesthetic that looks nice on a shelf, the excess material in the top portion of the bag is folded into the interior of the bag to form a false side gusset. To allow for such folding the bag, in desirable embodiments, side edges of a first and second web forming the bag angle inward at between about 30 degrees and about 60 degrees at a top portion transition point on the bag.

BACKGROUND

People rely on disposable absorbent garments in their everyday lives,including such garments as adult incontinence products, enuresis pants,training pants, and diapers. Many manufacturers seek to better meet theneeds of users of such products. With certain products, such as adultincontinence underwear and enuresis pants, it is important that thegarments look and feel as much as possible like “regular” underwear topromote an improved sense of normalcy to the wearer who suffers fromincontinence or enuresis. Additionally, purchasers and users of suchproducts are frequently embarrassed about their condition and abouthaving to purchase products to deal with their incontinence or enuresiscondition.

Currently, the most common method for obtaining incontinence andenuresis underwear is by purchasing relatively large bags in retailstores. Such conventional packages of incontinence and enuresisunderwear are opaque or mostly opaque, which some purchasers mayperceive as overly “diaper-like” or too strongly connoting the presenceof a personal care absorbent product directed to a urinary condition.Such conventional packaging bears little resemblance to the packaging inwhich durable clothing is sold. There is a need for a package ofincontinence or enuresis underwear that better resembles a package ofdurable underwear so as to improve the feeling of normalcy for thepurchaser/user. There is also a need for a package of incontinence orenuresis underwear that allows the potential purchaser to see selectedfeatures of the underwear, such as, for example, cloth-like materialused to make the underwear, elastic waistbands, and back-labelindicators.

Attempts have been made in the art to provided windowed packages toallow consumers to inspect the absorbent garments contained within thesealed packages prior to purchase. However, the prior art does notoptimally provide for targeted display and/or obscurement of particularfeatures of pants, particularly with larger underwear such asincontinence and enuresis underwear, some of which frequently requiremultiple folds in both directions to efficiently configure the underwearfor commercial packaging and sale.

Durable clothing and other bulky goods are often sold in a packagesystem that combines a rectangular carton inside a poly bag to allow fordisplaying targeted displays of features while still maintaining theproducts in the correct position in the package. Many bags also requirea header banner for branding and hanging the package on retail hooks.

When a standard flat bag is placed on a 3-dimensional carton or bulkygoods, the result is prominent “dog ears” protruding from the sides ofthe bag header. This is due to the fact that the flat bag width must besignificantly wider than the front face panel of the carton or good, inorder to accommodate the depth dimension of the carton. This causessignificant difficulties in merchandising the finished packs on shelf,as packs interfere with one another when they are placed side-by-side.The aesthetics are also generally considered to be undesirable.

One way of eliminating the protruding “dog ears” is to utilize a sidegusset bag. This method of bag formation tucks excess poly in the topseal, and creates a much narrower top banner, while maintaining thenecessary bag circumference to accommodate the carton. This problem withthis approach is that side gusset bags are typically used in bulk, loosefill applications such as dog food or lawn fertilizer, and as such theonly machines currently available in market to produce this style of bagrequire extremely heavy and rigid laminate film types. This look andfeel is decidedly ill-suited to the merchandising of underwear andabsorbent-type products.

A packaging structure is needed that can be produced using soft filmswhich allows a 3-dimensional or bulky contents to fit in a bag forstoring bulk goods without undesirable aesthetics.

SUMMARY

To better meet the above-described unmet needs in the art, a new packageis disclosed herein. Generally, a new package for storing bulky goods isdisclosed. The package is formed from a bag having a width and depth atits base portion and meeting at a top edge, the top edge having nodepth. Due to the top edge having no depth, the width of the material onthe top portion of the package extends out further than the width of thematerial on the base portion. To create a package having streamlinedaesthetic that looks nice on a shelf, the excess material in the topportion of the bag is folded into the interior of the bag to form afalse side gusset. To allow for such folding the bag extends out at acertain angle in the top portion to allow for proper and streamlinedfolding of the bag.

In one embodiment, a package is constructed from bag sealed together ata pair of side edges. The bag may be formed from a first web and secondweb sealed together at the pair of side edges. The bag includes a baseportion having a depth and a first width at the base portion forming acavity between the first web and second web. The bottom edges of the bagportion of the bag may be folded together to provide a bottom to thebag. The bag also includes a top portion. The top portion of the bagextends from a top portion transition point adjacent the base portion ofthe bag to a top edge. The bag has no depth at a top edge of the bag anda second width at the top portion transition point, wherein the secondwidth is greater than the first width. The excess material formed in thetop portion of the bag is folded and tucked into the interior of the bagto provide a bag having a clean appearance on shelf. Typically, toprovide a clean package on the shelf, the side edges of the first weband second web angle inward at between about 30 degrees and about 60degrees at a top portion transition point on the bag. In a desirableembodiment, the side edges of the first web and second web angle inwardat between about 40 degrees and about 50 degrees at a top portiontransition point on the bag. In another desirable embodiment, the sideedges of the first web and second web angle inward at about 45 degreeangle provides for a desirable fold appearance.

In another embodiment, a package is constructed from a bag and a housingportion to store articles. The housing portion includes a housing depth,housing width, and housing height, the housing portion having an openingat its top. The bag formed from a first web and a second web sealedtogether at a pair of side edges. The bag includes a base portion havinga depth and a first width at the base portion forming a cavity betweenthe first web and second web. The bottom edges of the bag portion of thebag may be folded together to provide a bottom to the bag. The bag alsoincludes a top portion. The top portion of the bag extends from a topportion transition point adjacent the base portion of the bag to a topedge. The bag has no depth at a top edge of the bag and a second widthat the top portion transition point, wherein the second width is greaterthan the first width. The excess material in the top portion of the bagis folded and tucked into the interior of the bag to provide a baghaving a clean appearance on shelf. Typically, to provide a cleanpackage on the shelf, the side edges of the first web and second webangle inward at between about 30 degrees and about 60 degrees at a topportion transition point on the bag. In a desirable embodiment, the sideedges of the first web and second web angle inward at between about 40degrees and about 50 degrees at a top portion transition point on thebag. In another desirable embodiment, the side edges of the first weband second web angle inward at about 45 degree angle provides for adesirable fold appearance.

In desirable embodiments, the housing portion has an opening at a top ofthe housing portion for displaying and removing articles. A feature ofthe articles stored within the housing extends through the opening ofthe housing portion and is visible to a consumer.

In other desirable embodiment, the bag includes a header strip. In someembodiments, a hole in the header strip enabling the package to be hungon a pin or rod on a display rack in a first shelf configuration. Theheader strip has a header strip width that may desirably besubstantially similar in width to the first width of the base portion ofthe package. In other embodiments, a header strip width that may begreater or smaller in width than the first width of the base portion ofthe package.

Use of a housing portion within the bag allows for two types of storageconfigurations of the packaging. A hole in the header strip enables thepackage to be hung on a pin or rod on a display rack in a first shelfconfiguration. In this embodiment, the housing portion would have a flatbottom enabling the package to be placed on a shelf in a second shelfconfiguration. Having a package with two types of shelf configurationprovides more flexible position on the store shelf.

DETAILED DESCRIPTION

Reference to the Figures shall be made in describing various aspects andembodiments of the invention. It should be noted that the embodimentsdepicted in the Figures and described herein are merely representativeexamples of the pants and package of the invention. The various aspectsand embodiments of the present invention are suitable for use with anygoods. In some embodiments, adult incontinence pants, prefasteneddisposable diapers, disposable swim pants, disposable training pants,disposable enuresis garments, and the like may be used with the package.

Generally, a new package for storing bulky goods is disclosed. Thepackage is formed from a bag having a width and depth at its baseportion and meeting at a top edge, the top edge having no depth. Due tothe top edge having no depth, the width of the material on the topportion of the package extends out further than the width of thematerial on the base portion. To create a package having streamlinedaesthetic that looks nice on a shelf, the excess material in the topportion of the bag is folded into the interior of the bag to form afalse side gusset. To allow for such folding the bag extends out at acertain angle in the top portion to allow for proper and streamlinedfolding of the bag.

Turning to FIGS. 1-3, a package 10 is constructed from bag 12. The bagmay be formed a tube from at least one material web and sealing tube ata pair of side edges. As illustrated, the bag is formed from a first web14 and a second web 16 sealed together at a pair of side edges 18, 20.The first and second web 14, 16 may be sealed at the side edges 18, 20by any means known to those skilled in the packaging art. For example,in one embodiment, the first and second web 14, 16 will be sealed withpinch seal, or an adhesive seal. When sealing with an adhesive, a hotmelt adhesive is preferably used for sealing the side edges of the web.Ultrasonic or heat sealing may also be used to seal the side edges 18,20 of the first and second web 14, 16 with or without a pinch seal andwith or without adhesive. In addition, any combination of sealingtechniques may also be used to seal the side edges 18, 20 of the firstand second web 14, 16 together.

In exemplary embodiment, each of the first and second web 14, 16 may beformed from a durable, flexible material suitable for such containmentand storage of materials. Examples of suitable materials for the firstweb and second web include, but are not limited to paper, aluminum foil,metalized films, coated films, printed films, co-extruded films,polyester films, polyolefin based films, white polyolefin based films,polyamide based films, copolymer films, multi-layer polymer films andfilms containing various polymer blends. Preferably, the first web andsecond web is polyolefin based, such as a monoweb polymer. One desirableembodiment would be polypropylene. Other examples include polyethyleneand blends of polypropylene and polyethylene and separate layers ofpolymers, and other intermediate extrusion layers can be utilized withthe separate woven polypropylene layer and the propylene outer layer.These polymers can be blended in combination or used in separate,distinct sheets.

In some embodiments, the first web 14 and second web 16 are formed fromthe same materials. In other embodiments, the first web 14 and secondweb 16 are formed from different materials.

The constructed bag 12 includes a base portion 22 having a depth D1 anda first width W1 at the base portion 22 forming a cavity 24 between thefirst web 14 and second web 16. Once filled with the contents of thepackage 10, the bottom edges of the first and second web 14, 16 of thebag 12 may be folded together to provide a bottom 26 to the bag 12.

The bag 12 also includes a top portion 28. The top portion 28 of the bag12 extends from a top portion transition point 30 adjacent the baseportion 22 of the bag 12 to a top edge 32. The bag 12 is sealed at thetop edge 32. The first and second webs 16, 18 may be sealed at the topedge 32 by any means known to those skilled in the packaging art. Forexample, in one embodiment, the web will be sealed with pinch seal, oran adhesive seal. When sealing with an adhesive, a hot melt adhesive ispreferably used for sealing the side edges of the web. Ultrasonic orheat sealing may also be used to seal the side edges of the bag with orwithout a pinch seal and with or without adhesive. In addition, anycombination of sealing techniques may also be used to seal the top edge32 of the first and second web 14, 16 together.

As illustrated in FIG. 3, the bag 12 has no depth at a top edge of thebag and a second width W2 at the top portion transition point 30,wherein the second width W2 is greater than the first width W1. Asdiscussed above, due to the top edge 32 having no depth, the excessmaterial 29 from the top portion 28 of the bag 12 extends out furtherthan the width of the material on the base portion 22 of the bag 12. Tocreate a package 10 having streamlined aesthetic that looks nice on ashelf, that excess material 29 of the top 28 portion of the bag 12 isfolded into the interior or cavity 24 of the bag 12 as illustrated inFIGS. 1 and 2.

To allow for the material of the top portion 28 of the bag 12 to foldproperly into the interior or cavity 24 of the bag 12, the first andsecond webs 14, 16 have a specifically designed structure. Asillustrated in FIG. 4, the formation of the side edges 18, 20 of boththe first and second web 14, 16 is the key to getting the polymer filmto fold into an inverted corner and lay flat is the angle at which theside of the bag 12 is cut. Typically, to provide a clean package 10 onthe shelf, the side edges 18, 20 of the first web and second web 14, 16angle inward at a transition angle 40 between about 30 degrees and about60 degrees at a top portion transition point 30 on the bag 12 to the topedge 32 of the bag 12. In another embodiment, the side edges 18, 20 ofthe first web and second web 14, 16 angle inward at a transition angle40 between about 40 degrees and about 50 degrees at a top portiontransition point 30 on the bag 12 to the top edge 32 of the bag 12. Inone desirable embodiment, the side edges 18, 20 of the first web 16 andsecond web 18 angle inward at a transition angle 40 of about a 45 degreeangle providing for a desirable fold appearance.

While the soft film is somewhat forgiving in the range of about 15degrees, any angle beyond that range will start to show undesirablepuckering at angles of less than 40 degrees, and incomplete tucking atangles greater than 50 degrees. Incomplete tucking or undesirablepuckering of the package results in a package that is less appealing toa consumer on shelf. Therefore, having a correct transition angle 40 information of the first and second webs 14, 16 allowing for folding ofthe bag 12 is critical to providing a package 10 capable of storingbulky goods and having a header strip for proper shelf aesthetics.

In desirable embodiments, the first and second webs 14, 16 forming thebag 12 are transparent materials, allowing a consumer to see thecontents of the package 10 for inspection. In other embodiments, thefirst and second webs 14, 16 are opaque.

Adjacent the top edge 32 of the bag 12 is an integral header strip 42.In some embodiments, a hole 44 in the header strip 42 enabling thepackage 10 to be hung on a pin or rod on a display rack in a first shelfconfiguration. The header strip has a header strip width W3 that maydesirably be substantially similar in width to the first width W1 of thebase portion 22 of the package 10. In other embodiments, a header stripwidth W3 that may be greater or smaller in width than the first width W1of the base portion 22 of the package 10.

In some embodiments, the package 10 includes a housing portion 50 tostore the articles. The housing portion 50 includes a housing depth,housing width, and housing height, the housing portion having an opening52 at its top. The housing portion 50 of the package 10 may be formed ofany suitable packaging material known to those skilled in the art, suchas, for example, paper, plastic film, paperboard, corrugated board,flexible polymeric material, semi-rigid plastic, or combinationsthereof. In one embodiment, the housing portion 50 at least in partcomprises a carton, such as a paperboard carton. The housing portion 50may optionally include one or more inserts disposed within the housingportion 50, such as a paperboard insert.

In a desirable embodiment, the housing portion 50 has an opening 52 atthe top of the housing portion 50 for displaying an article or good. Thearticles or goods 54 are positioned within the housing portion 50 suchthe at least one article 54 extends above the height of the housingportion 50, and such that at least a feature 56 of the article 54 isvisible through the transparent bag 12. For example, a feature 56 of thearticles 54 extends through the opening 52 of the housing portion 50 andis visible to a consumer.

As illustrated in the figures, the package 10 may further include aplurality of articles disposed within the housing portion 50. Inparticular embodiments, the articles may include disposable absorbentpants or durable absorbent pants for use with disposable absorbent pads.Examples of these types of articles suitable for incorporation intoparticular embodiment of the present invention include those disclosedin U.S. application Ser. No. 13/547,974 filed by Evenson et al. on Jul.12, 2012, U.S. application Ser. No. 13/933,235 filed by Vignali et al.on Jul. 2, 2013, and U.S. application Ser. No. 13/933,260 filed byEvenson et al. on Jul. 2, 2013, the contents of each of which is herebyincorporated by reference to the extent consistent herewith. Examples ofdisposable absorbent pants having certain aspects suitable forincorporation into particular embodiments of the present inventioninclude those disclosed in U.S. Pat. No. 5,745,922 issued May 5, 1998 toRajala et al., U.S. Pat. No. 6,240,569 issued Jun. 5, 2001 to Van Gompelet al., U.S. Pat. No. 6,702,798 issued Mar. 9, 2004 to Christoffel etal., and U.S. Pat. No. 7,604,624 issued Oct. 20, 2009 to Veith et al.,the contents of each of which is hereby incorporated by reference to theextent consistent herewith. Note that the disposable absorbent pantscould be provide in a permanently “closed” (i.e., pull-on style)configuration, a releasably and refastenably “closed” configuration, oran “open” (i.e., non-prefastened) configuration—any of which could beused in conjunction with the various embodiments of the presentinvention. While illustrated as a garment, any object or articlerequiring the package to have bulk may be stored within the packagedescribed herein.

Referring to FIGS. 2-3, in particular embodiments at least one garment60, such as at least two pants, of the plurality of articles ispositioned within the housing portion 50 such the at least one garment60 extends above the height of the housing portion 50, and such that atleast a portion of the a feature 56 of the garment 60 is visible throughthe transparent bag. In this way, it can in certain embodiments bepossible to highlight for a consumer the waistband region 70 of thegarment or article. The feature 56 of the garments 60 that isillustrated through the package is selected from cloth-like materialused to make the underwear, elastic waistbands, and back-labelindicators. Without intending to be limiting, the present inventors havediscovered that these particular dimensional relationships can inparticular embodiments optimize the balance between displaying desiredfeatures 56 of the product through the package bag 12.

The housing portion 50 may also be used to store components of the goodsthat are undesirable for the consumer to see or require more discretion.For example, in the type of product with having both a durable absorbentpants for use with disposable absorbent pads, the absorbent pads may bestored within the housing and not visible to a consumer. If storedwithin the housing portion 50, the absorbent pads cannot be seen andprovide more discretion to a consumer who purchases them at the storenormalizing the purchase and providing a better consumer experience.

In addition, use of a housing portion 50 within the bag 12 allows fortwo types of storage configurations of the packaging. A hole in theheader strip enables the package to be hung on a pin or rod on a displayrack in a first shelf configuration. In this embodiment, the housingportion 50 would have a flat bottom enabling the package 10 to be placedon a shelf in a second shelf configuration. Having a package 10 with twotypes of shelf configurations provides more flexible positioning on thestore shelf.
